The associations between disease outcomes and obesity predictors (BMI z-score and body fat %), were analyzed through univariate analysis and the odds ratio (OR) were calculated with 95% confidence intervals (CI). In addition to the univariate analysis, multiple logistic regression was also performed to further investigate the associations of obesity predictors and disease outcomes adjusting for confounders and stratifying by significant effect modifiers. Statistical significance was set at P < 0.05.
